ROVING MECHANISM.

SPECIFIGATION forming part of Letters Patent No. 744,306, dated November17, 1903.

To all whom it may concern:

Beit known that I, NAROISSE N. S. DAUDE-.

pose; but the flaring shape of the trumpet re-.

sults in accumulating and compressing the fiber and foreign matter inthe concavity adjacent the trumpet-passage, whereby the latter openingbecomes so restricted that the -rove is either attenuated or completelybroken.

The above disadvantage is obviated by the novel auxiliary mechanismhereinafter described, and illustrated in the accompanying drawings,wherein like reference-numerals indicate like parts throughout theviews.

Figure 1 is a front elevation of a section of a spinning-frame minus allthe drawing-rollers except a part of the back lowerroller embodyingmyinvention; Fig. 2, a similar view of the same, showing the parts'in adifferent position; Fig. 3, a transverse section of a portion of theframe, taken on line .70 a: of Fig. 1, omitting the stop mechanism;Fig'.4, a silni-' lar sectionof the same, including the stopv mechanism, butomitting the gearing; Fig. 5, a plan View of the roving-bar-actuatingFig. 6, a similar broken view of the bars and rollers, and Fig. 7 adetail perspective'view of one of the novel ring-couplets. I

In the drawings, 1 is the beam of a spinning or twisting frame 2,provided with the thread-board 3 and guide eyes or wires '4. Theroller-stands 5 5 carry the usual drawing-rollers 6 7 and cap-bar 8, inthe rear of which, mounted upon the creel or the frame, is theroving-bobbin 9, bearing the roving 10.

The lower back roller 7 carries upon its extremity a driving-pinion 11,which meshes with a gear 12, mounted on a stud 13, carried Heretoforecertain funnel-1 other. 7 provided with a longitudinal slot 34 and thein a bracket 14, which is fastened to a support- 15. On the inner end ofstud13 is gear 16, which meshes with gear 17'on stud 18,

T mounted in bearings 19, fastened to brackets 20 on support 15. Alsosecured to stud 18 is a cam 21, provided with an irregularcircumferential slot or channel 22. Pivoted upon support 15 by means ofpin 23 is a lever 24, provided at its end with a downwardly-projectingroller 25, which registers with the channel 22. To the end of lever24tis pivoted an arm 26, fixed to an extension-piece 27, vwhich in turnis secured to the rear rovingbar 28. It will be noted that in mystructure the roving-bar is in two parts 28 29, or rather comprises twocontiguous bars. A pin 30 projects from the end of the'arm 26, to whichis fixed the end of a retractile spring 31, whose opposite endis fixedto a pin in the rollerstand 5. Another retractile spring is securedatone end to extension-piece 27 and at its opposite end to a pin 50,projecting downward from the forward roving-bar 29.

The roving-bars 28 29 are slidably mounted in the roller-stands 5, whichrise at intervals upon the beam 1. Upon the rear bar 23 rise atintervals the flaring rings 51. In transverse alinement with theserings, but upon the outer roving-bar 29, rise semicircular flanged rings33, whose smallest radii are -much less than the minimum radii of therings 51.' Each of the above ring pairs is traversed by a roving 10. Thespring 32 has a tendency to slide one roving-bar past the To precludethis result, the bar 28 is bar 29 with a pin 35, registering with theslot,

thus limiting the sliding movement. mechanism with bar and rollersremoved;

A downwardly-projecting plate 36 is fixed to the bar 29, adapted tostrike against the upturned end of a lever 37, fulcrumed at 38 The endof this lever is depressed by a weight 4.0 and is limited againstexcessive depression by vertical post 41, fixed to the frame 2.

The operation of the parts involved in this invention is as follows: Theseries of rovings 10 pass from their bobbins 9 to the drawingrollers 6 7through their respective guidingring couplets 51 33, arranged in series.The roller-pinion 11 drives the gear.17 through the intermediate gears12 and 16, thereby rein a standard 39, mounted upon the beam 1.

volving the channeled cam 21, which longitudinally reciprocates the bar26. Both bars 28 and 29 advance together, as shown in Fig. 1, until theprojecting plate 36 on bar 29 contacts with the upturned end of lever 37and temporarily interrupts its advance. Thus the rear rings 51 come outof alinement with the front rings 33, and the rovings 10 are drawn clearof the latter, Figs. 2 and 6, the rear bar 28 progressing independentlyof the front bar until the end of slot 34 of the former contacts withthe pin 35 of the latter, whereupon the plate 36 trips and passes overthe lever 37, and the tension of spring 32 instantly forces the bar 29forward, and its rings are thereby instant-1y brought into alinementwit-h and accompany the rings 51 to the end of the travel of theroving-bars. The return of the roving-bars toward the right is effectedby means of the rotating cam 21, both ring series being in alinementthroughout the return traverse. The result of the ring interactionduring the reciprocation of the roving-bars is to intermittently engageand disengage the semicircular rings with the roving, thereby preventingthe accumulation of lint in the restricted orifices of the semicircularrings and without deranging the regularity of the reciprocating feedthrough the relatively stationary annular rings.

The function of the spring 31 is to retain the roller 25 against thewall of the diagonally-disposed circumferential channel 22. Thisovercomes the possibility of a momentary dwell of the said roller uponeach halfrevolution of the cam 21. By this means is avoided the creationof circular ridges upon the drawing-rollers 6, due to a more prolongedcontact with the roving at one point of the roller-surface than atanother.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a roving mechanism, the combination with a roving-bar of annularguides thereon, a second bar adjacent the first, semi-annular guidesupon the second bar in alinement with the annular guides, and means forintermittently forcing the semi-annular guides out of alinement.

2. In a roving mechanism, the combination with a roving-bar of annularflaring guides thereon, a second bar adjacent the first, semiannularflaring guides upon the second bar in alinement with the annular guides,and means for intermittently forcing the semi-annular guides out ofalinement.

3. Ina roving mechanism, the combination with a roving-bar of guidesthereon, a second bar adjacent the first, guides upon the second bar andmeans upon the'bars for normally retaining the guides in alinement witheach other.

4. In a roving mechanism, the combination with a roving-barof guidesthereon, a second bar adjacent the first, guides upon the second bar,means upon the bars for normally retaining the guides in alinement witheach other and means contacting with one of the bars to force the twosets of guides out of alinement with each other.

5. In a roving mechanism, the combination with a roving-bar of guidesthereon, a second bar contiguous with the first, guides upon the secondbar and retractile means upon the bars for normally retaining the guidesin alinement with each other.

6. In a roving mechanism, the combination with a roving-bar of guidesthereon, a second bar adjacent the first, guides upon the second bar,means for normally retaining the guides in alinement with each other,means upon the second bar for contacting with a lever, a lever mountedadjacent the second bar, and in the line of travel of the contactingmeans thereof to force the two sets of guides out of alinement with eachother, and means for reciprocating the bars.

7. In a roving mechanism, the combination with a spinning-frame ofsupports upon the frame, two roving-bars slidably mounted in thesupports, guides at corresponding intervals upon both bars, means fornormally retaining the guides in transverse alinement with each other,means upon one of the bars for contacting with a lever, a lever-supportmounted upon the spinning-frame, a gravitylever pivoted to thelever-support, and in the path of the lever-contacting means to forcethe two sets of guides out of alinement, and means for reciprocating theroving-bars.

8. In a roving mechanism, the combination with a standard of a leverpivoted thereto, a roller mounted upon the free end of the lever, a camalso mounted upon the standard and provided with a diagonally-disposedannular channel in which the roller travels, an arm pivoted to the freeend of the lover, a rovingbar connected to the end of the arm, andretractile means upon the bar for forcing the roller into closeengagement with one side of the annular channel.

In testimony whereof I have aifixed my signature in presence of twowitnesses.
